Letters Patent No. 86,004, dated Jamm/ry 19, 1869.

IIVEPROVEMENT IN PHI!v MANUFACTURE OF WROUG-HT-IRON'.

The Schedule referred to in these Letters Pate t n making P of 'f To all whom it may concern Be it known that I, T. O. COLEMAN, of Louisville, in the .county of Jefferson, and State of Kentucky, have invented a new and improved Manufacture of Wrought-1ron; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make 'and use the same.

This invention relates to an improved process for the manufacture of iron; and consists in the manner of mixing and combining iron-cinders or other flux, with molten pig-metal, previously to working it into puddle-balls.

I melt pig-iron and iron-cinders, or other flux, in proper proportions, in a cupola or furnace previous to the admission of the same to the puddling or reverberatory furnace, by adding the cinder or other flux after the pig-metal has been melted. I then tap the cupola and admit the compound into the said puddling-fiirnace, where the stirring and boiling-operation is carried on in the old and well-known manner, and more cinder or other flux may be added at thev time of tapping into the puddling-furnace.

I have found, in practice, that this method admits of a better fluxing of the substance than can be efiected Patent- Mixing iron-cinder or other fluxvwith pig-metal, in the cnpola or furnace, previous to and at the time of transferring it to the reverberatory furnace, substantially as and for the purpose specified.

T. o. COLEMAN.
